Description

[Detailed Description of the Invention] The present invention relates to a swing prevention device that prevents swinging of a hanger door roller having a door suspended from an opening of a building during running.

In general, a hanger door roller whose door body is suspended from an opening in a building is constructed by inserting the door from below between two rails that are installed opposite each other with a gap wider than the diameter of the door roller, and straddling the rails. It was designed to be worn as a cover.
In order to allow the hanger door roller to run smoothly without shaking, conventionally, as shown in Figure 3, a square sliding body was formed integrally with the hanger door roller, which was located between the two rails to prevent sideways shaking. However,
Although this method can prevent the door roller from swinging horizontally, it cannot prevent the door roller from swinging vertically. In addition, when the hanger door roller is straddled over the rail, the sliding body is inserted between the rails together with the door roller. Next, it must be rotated horizontally above the rail to be positioned between the two rails, so if it is not rotated accurately to a position facing between the rails, the square sliding body will slide over the opposite end of the rail. The disadvantage was that the door wheel could not be straddled over the rail because it would run over the edge, making it difficult to operate.

The present invention was devised to eliminate these drawbacks in view of the above-mentioned actual situation, and although it is designed to position a regulating body between the rails to prevent runout, We have developed a hanger door swing prevention device that allows the hanger door roller to be easily straddled on the rail without any troublesome operations, and that also prevents the hanger door roller from swinging horizontally as well as vertically to ensure smooth running. In particular, the vibration prevention regulating body has a short side that can be inserted with a small gap between the two guide rails, and a long side that is appropriately longer than the gap. , a protrusion extending wider than the gap between the two guide rails is formed along the lower part of both sides of the long side, a recess that can be engaged with the mounting boss part of the door axle is formed on the upper surface, and a concave part that can be engaged with the mounting boss part of the door axle is formed on the upper surface. The door roller is mounted on the upper surface of the regulating body at a position where the long side of the regulating body is parallel to the door axle, and the door roller can be inserted between both rails. The present invention is characterized in that the mounting boss portion engages with the recessed portion so that the door roller can run on both rails.

The structure of the present invention will be explained based on an embodiment shown in the drawings. Reference numeral 1 is a folding door formed by foldably connecting door bodies 3, 3 via a center stile 2. A mounting shaft 4 is erected on the upper part of the door body 3 on the hanging side and the traveling side of the folding door 1, and a mounting boss portion to which a pair of door wheels 5, 5 is pivoted is attached to the upper end of the mounting shaft 4. 6a is attached to the door wheel shaft 6 so as to be horizontally rotatable, thereby forming a hanger door wheel 7.

8 is an upper frame, 9 is a lower frame, and 10 and 11 are vertical frames, which constitute a door body 12. On the lower surface of the upper frame 8 are rails 13, 13, and the door roller 5.
are placed opposite each other with an interval wider than the diameter of the
A rising portion 13a is formed on the opposing edge. And on the rails 13, 13 there are door wheels 5, 5.
By straddling the folding door 1, the folding door 1 can be opened and closed within the door frame 12.

Reference numeral 14 denotes a vibration prevention regulating body that is pressed against the mounting shaft 4, and the regulating body 14 has a short side 14a that can be inserted with a slight gap between the rails 13, 13.
and a long side 14b that is appropriately longer than the interval,
Both rails 1 are installed along the bottom of both sides of the long side 14b.
A protrusion 14c is formed that protrudes wider than the distance between the ridges 3 and 13, and a recess 15 that can be engaged with the mounting boss 6a of the door axle is formed on the upper surface.

The regulating body 14 is held upward by a biasing bullet 16 loaded on the mounting shaft 4, and is held at a position where the long side 14b of the regulating body 14 and the door axle shaft 6 are parallel. The door rollers 5, 5 are mounted on the upper surface of the regulating body 14, and the door rollers 5, 5 can be inserted between the rails 13, 13, and the long side 14b of the regulating body 14
At the position where the door axle 6 and the door axle 6 are perpendicular to each other, the mounting boss 6a engages with the recess 15 of the regulating body 14, and the door wheel 5,
5 is configured to be able to travel on rails 13, 13.

In the above configuration, when the hanger door roller 7 attached to the door body 3 of the folding door 1 is straddled over the rails 13, 13, first, the regulating body 14 is applied to the biasing force of the biasing bullet machine 16. It is pressed down against the pressure and rotated to a position where the long side 14b of the regulating body 14 and the door axle shaft 6 are parallel, and the door wheels 5, 5 are placed on the upper surface of the regulating body 14, and in this state, the hanger door roller 7 is placed on the rail. 13, 13 and moves upward, the distance between the rails 13, 13 is wider than the diameter of the door roller 5, and the short side 14a of the regulating body 14 is also smaller than the distance between the rails 13, 13, so the door roller 5 , 5 can be easily inserted between the rails 13, 13, and the long side 14b of the regulating body is aligned with the rail 1.
3, 13 between both rails 13, 13, and the protrusion 14c at the bottom of the long side 14b is inserted between the rails 13, 13.
13 is brought into contact with the lower surface. Next, the door wheels 5, 5 are placed at a position where the long side 14b of the regulating body 14 and the door axle shaft 6 are perpendicular to each other.
When the door axle 6 is rotated, the mounting boss 6a of the door axle 6 is pushed into and engaged with the recess 15 of the anti-swing regulating body 14 by the bias of the bullet 16, and the door wheels 5, 5 are attached to the rail 1.
3 and 13, the hanger door roller 7 can be easily straddled over the rails 13 and 13 without any particularly troublesome operations. Since this regulating body 14 does not need to be inserted and rotated above the surfaces of the rails 13, 13, the long side 14b can be formed longer than the interval between the rails 13, 13, and it protrudes at the bottom of both sides of the long side 14b. The strip 14c can be formed, the play in the width direction with the rails 13, 13 can be minimized, and the long side 1
The protrusions 14c at the bottom of both sides of 4b are the rails 13, 13
By coming into contact with the lower surface, the upward movement of the hanger door roller 7 can be restricted, horizontal and vertical vibrations can be prevented simultaneously, and smooth running can be ensured.

In short, the present invention provides an upper part of the door body in a hanger door roller in which the door body is suspended from two upper guide rails installed oppositely on the frame of the opening with a gap wider than the diameter of the door roller. A mounting boss that horizontally supports a door axle with a pair of door wheels attached to both ends is attached to the upper end of the upright mounting shaft, and is rotatable in the horizontal direction. A swing prevention regulating body located between and traveling together with the door roller is biased toward the door roller side, and the swing prevention regulating body is
A short side that can be inserted with a slight gap between the two guide rails, and a long side that is appropriately longer than the gap, and along the lower part of both sides of the long side, the length of the guide rail is longer than the gap between the two guide rails. A widely protruding protrusion is formed, and a recess that can be engaged with the mounting boss portion of the door axle is formed on the upper surface, and the door wheel is attached to the upper surface of the regulator at a position where the long side of the regulator is parallel to the door axle. The door roller can be inserted between both rails, and the mounting boss engages with the recess of the regulator at a position where the long side of the regulator is perpendicular to the door axle, and the door roller runs on both rails. Because of the structure, the door roller can be rotated independently of the regulating body even though the regulating body to prevent swinging is positioned between the opposing rails, and the door roller can be moved automatically. In addition to being a gauge that can be locked in place and easily straddled over the rail without any troublesome operations, the regulating body can be formed to be longer than the rail spacing, and protrude wider than the rail spacing at the bottom. Since the protrusions can be formed to prevent horizontal vibration as well as vertical vibration, it is possible to reliably prevent vertical vibration.
